| coated vesicles | Vesicles formed when cell-membrane coated pits (coated pits, cell-membrane) invaginate and pinch off. The outer surface of these vesicles is covered with a lattice-like network of the protein clathrin. Shortly after formation, however, the clathrin coat is removed and the vesicles are referred to as endosomes. (12 Dec 1998) |
| tablets, enteric-coated | Tablets coated with material that delays release of the medication until after they leave the stomach. (12 Dec 1998) |
| enteric-coated | A term designating a special coating applied to tablets or capsules which prevents release and absorption of their contents until they reach the intestines. (18 Nov 1997) |
| enteric coated tablet | An oral dosage form in which a tablet is coated with a material to prevent or minimise dissolution in the stomach but allow dissolution in the small intestine. This type of formulation either protects the stomach from a potentially irritating drug (e.g., aspirin) or protects the drug (e.g., erythromycin) from partial degradation in the acidic environment of the stomach.
